blue bleemast Vs beta bleemcast
 

Some web site are talking about a new version a bleemcast with support a full psx game (???) : blue bleemcast (i think it was only for one game) .

Is there a difference with beta version ?

blue bleemcast and beta are the same thing. The cracked beta is actually cracked from the blue bleemcast beta. As i remember there were four colour coded dcs and betas- blue,green,orange,red? At first they were suppose to be different- blue beta works on certain dcs and so on. But whoever released the cracked beta said that they were all the same.
Someone correct me if i'm wrong...

yup. that's what it seems apparently. the cracked version's no different from all the color-codes.
